(菜鳥來動手)SpringMVC+Spring+Mybatis整合(第三天) SSM框架整合

前一段寫了前2天的內容,本來想一個框架一個框架網上增.後來發現不好整... 這次參考網上的文章,一次將3個框架整合到一起.記錄下來.

大體步驟:

1.新建maven web 項目

2.引入jar包

3.寫業務代碼

4.配置文件

5.測試

開始:

一:

1)第一步直接上圖,new maven project

2. 這裏選擇 maven-archetype-webapp, 但是這個出來默認的是web module是2.3,jdk是1.5,貌似要使用自定義catalog纔可以自己設置.

3.這個基本都是隨便寫了. artifactid 是項目名稱

4. finish後,生成目錄結構如下圖,可以看到沒有src的路徑,

5.修改 jre lib位置,不使用默認的

7. 修改後,再看目錄, 已經有src目錄了, 可能是個bug導致的.

8.到project facets, 修改jdk版本和 web module,發現報錯 cannot change version of project facet dynamic web module to 3.0

9.打開navigator視圖,到settings文件夾下,將裏面的配置文件中的JDK版本 1.5,改到1.7, web module 2.3 改到 3.0

10. 還要修改下web.xml 修改後如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xmlns="http://java.sun.com/xml/ns/javaee" 
         xmlns:web="http://java.sun.com/xml/ns/javaee" 
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
</web-app>

第一步完成,開始第二部.

二:引入jar包

這個就比較簡單,需要的jar包,引入到pom.xml就可以了,直接貼上代碼

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

三:配置文件

1.main-content.xml , 相當與 application-content.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd">
  
  <import resource="spring-mybatis.xml" />
</beans>

2.spring-mybatis.xml, 用於配置數據源

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans  
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  
                        http://www.springframework.org/schema/context  
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd">
	<!-- 自動掃描 -->
	<context:component-scan base-package="com.xm.common" />
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">

	</bean>

	<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自動掃描mapping.xml文件 -->
		<property name="mapperLocations" value="classpath:com/xm/common/mapping/*.xml"></property>
	</bean>

	<!-- DAO接口所在包名，Spring會自動查找其下的類 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.xm.common.dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>

	<!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>

</beans>

3.spring-mvc.xml , 用於配置 springmvc

<?xml version="1.0" encoding="UTF-8"?>

       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"
	default-lazy-init="true">

	<!-- DispatcherServlet Context: defines this servlet's request-processing 
		infrastructure -->

	<!-- Enables the Spring MVC @Controller programming model -->
	<mvc:annotation-driven />
	<context:component-scan base-package="com.xm.common.controller" />


	<!-- Resolves views selected for rendering by @Controllers to .jsp resources 
		in the /WEB-INF/views directory -->
	<beans:bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value="/WEB-INF/jsp/" />
		<beans:property name="suffix" value=".jsp" />
	</beans:bean>
	
	<!-- file upload -->  
<!-- 	<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />   -->
</beans:beans>

4.web.xml ,配置 springmvc及一些其他的

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee"

	version="3.0">
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:main-context.xml</param-value>
	</context-param>

	<!-- Character Filter -->
	<filter>

	</servlet>
	<servlet-mapping>
		<servlet-name>SpringMVC</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

四:代碼

model

package com.xm.common.model;

import java.io.Serializable;

public class User implements Serializable {

	private static final long serialVersionUID = 1L;
	
	private Integer id;
	private String userName;
	private String password;
	private Integer age;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	
	@Override
	public String toString() {
		return "User [id=" + id + ", userName=" + userName + ", password="
				+ password + ", age=" + age + "]";
	}
    
	
}

dao

package com.xm.common.dao;

import com.xm.common.model.User;

public interface UserDao {
    User selectByPrimaryKey(Integer id);
}

mapping

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.xm.common.dao.UserDao">
	<resultMap id="BaseResultMap" type="com.xm.common.model.User">
		<id column="id" property="id" jdbcType="INTEGER" />
		<result column="user_name" property="userName" jdbcType="VARCHAR" />
		<result column="password" property="password" jdbcType="VARCHAR" />
		<result column="age" property="age" jdbcType="INTEGER" />
	</resultMap>

	<sql id="Base_Column_List">
		id, user_name, password, age
	</sql>
	<select id="selectByPrimaryKey" resultMap="BaseResultMap"
		parameterType="java.lang.Integer">
		select
		<include refid="Base_Column_List" />
		from user_t
		where id = #{id,jdbcType=INTEGER}
	</select>
</mapper>

service

package com.xm.common.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.xm.common.dao.UserDao;
import com.xm.common.model.User;


@Service("userService")
public class UserService {
	@Autowired
    private UserDao userDao;  
	
    public User getUserById(int userId) {  
        return this.userDao.selectByPrimaryKey(userId);  
    } 
}

controller

package com.xm.common.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.xm.common.model.User;
import com.xm.common.service.UserService;

@Controller
@RequestMapping("/user")
public class UserController {
	@Autowired
	private UserService userService;
	
	@RequestMapping("/showUser")
	public String toIndex(Model model,Integer userId){
		User user = this.userService.getUserById(userId);
		model.addAttribute("user", user);
		return "showUser";
	}
}

showUser.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
	<title>測試</title>
  </head>
  
  <body>
    ${user.userName}
  </body>
</html>
